To propagate the further growth of that fruit
The purpose of fruit on a plant is to protect and disperse seeds for reproduction.
The fruit of a plant or tree serves the purpose for reproduction. It is frequently used as a tool which depends upon animals wishing to eat it, then the animal will help scatter the seeds around from watse..etc.
protect the seeds also as the fruit rots it provides some nourishment for the seedling
Plants have evolved fruit to better spread seeds. The fruit is a tremendous waste of energy to produce, only to be eaten by predators/scavengers. The current line of thought is that animals eat the fruit and seeds, wander away, and poop the seeds out (with fertilizer!) spreading the seeds over a great distance
Fruit contains the seeds that will produce new plants. Its purpose is to protect the seeds for reproduction. Fruit is the fleshy part, or ovary, of the plant.
Usually the fruit is to nourish the seed contained within long enough for the seed to germinate. However, some plant seeds can survive a passage through an animal's intestine. These plants produce fruit which is attractive to animals which then disperse the seeds through their feces.
All fruits have seeds, that is what makes a fruit a fruit. :)
The most widely eaten variety of banana, the Cavendish, does not have seeds. It is a mutant which is cultivated precisely because people prefer not to have seeds in their bananas (just as they like seedless grapes, watermelons, etc.). However, bananas with seeds do exist. All fruit originally have seeds, because that is the evolutionary purpose of fruit, to get animals to disperse the seeds of the plant. Fruit are not going to evolve unless they serve some purpose for the plants upon which the fruit grows. However, you can get a seedless mutation, and since we humans like the seedless fruit, we cultivate it.
A strawberry is a fruit: it has seeds. It's the only fruit with seeds on the outside.
an apricot is a fruit because every fruit has a seeds and apricots have seeds
Strawberries have seeds outside the fruit.
There aren't any fruits without seeds. If it didn't have seeds, it wouldn't be a fruit. You might think bananas don't have seeds but they have seeds.
